This software is a Java-based board game that is both free and open source.
The game itself is pretty easy to understand. The board is divided into rectangular tiles, each of which has a color. Adjacent tiles with the same color combine to form regions. At the start of the game, each player begins with a corner region. The two players start in opposing corners, and the current player's region is marked with an X.
During the game, players take turns selecting new colors for their regions. They're not allowed to pick the color of their own region or the color of the other player's region. When a player selects a new color for their region, all adjacent regions that have the same color are added to it, as well as regions that have been cut off from the other player's region.
The game continues until one player has conquered the entire board. The winner is the player with the biggest region. Overall, Java Color Expansion is a fun and easy-to-learn game that can be enjoyed by players of all skill levels.
